title: [Sporadic and group imported cases of hepatitis E in St. Petersburg].
abstract: OBJECTIVE
  Carry out retrospective clinical-epidemiological analysis of sporadic and group cases of acute HE morbidity in St. Petersburg (2000 - 2012). MATERIALS AND METHODS; Medical histories of 11 patients with sporadic morbidity (9 males and 2 females, average age 36 +/- 18) and 13 patients involved in group HE morbidity were analyzed. Acute hepatitis E diagnosis was established based on common clinical-epidemiological criteria confirmed by results of biochemical study and data of objective examination. Hepatitis E etiological membership was confirmed by detection in patient blood sera of specific marker of infection--anti-HEV G and M classes with laboratory exclusion of hepatitis A, B and C.
  
  
  RESULTS
  Study of epidemiological anamnesis of patients showed that 8 of them were migrants from countries with tropical and subtropical climate. 3 patients were residents of St. Petersburg. In the end of December 2011 and in January 2012 a group HE morbidity was registered among those who had arrived to study in St. Petersburg from India (Mumbai) in a group exceeding 200 individuals. Clinical characteristic of acute HE during sporadic and group morbidity is given.
  
  
  CONCLUSIONS
  The presence of sporadic and group HE morbidity in St. Petersburg indicates the necessity to register these situation in organization of protection of the territory of Russia from endogenous HE.
